The cleaners came Friday to wash the blood out of Elmer and Viola Stacy\'s carpet.

Now the rural Davenport couple hopes someone will tell them whose blood it was.

\"We are both in our 90s, and we are tired,\" Elmer said. \"It was an exhaustive experience.\"

Police called in bloodstain experts and specially trained dogs when they arrived at the Stacys\' home Tuesday to find gore splattered in the kitchen and several other rooms, mostly on the floors and low on the walls.

So far, all they can tell is that the blood is human, and that it \"was almost all over the house,\" Scott County Sheriff\'s Capt. Mike Brown said. \"It looked bad. It makes you take a step back and say, \'Whoa, what happened?\' \"

Elmer and Viola say they are fine. They apparently were home when the mess was made. Brown said Elmer and Viola were checked by a doctor. Their DNA will be compared with the blood.

The house was as tidy as before the mess was discovered.

\"It\'s just bizarre,\" Brown said. \"We have a ton of questions.\"

Rex Sparks, a bloodstain pattern analyst with the Des Moines Police Department, went to Scott County to help with the investigation. The couple stayed next door with a daughter in the interim.

Authorities wonder if someone injured in a traffic or a hunting accident wandered into the home.

If so, Elmer and Viola heard nothing.

Cadaver dogs and their handlers came up empty in the surrounding area.

The barricades that blocked access to the house, near Interstate Highway 280 and U.S. Highway 61, are gone now. But the questions remain.

\"We\'re back in our house,\" Elmer said. \"But it\'s still a mystery.\"
